DESCRIPCIÓN DETALLADA DE LA INVENCIÓNDETAILED DESCRIPTION OF THE INVENTION
A continuación se hará una descripción más detallada del dispositivo de la invención, tomando como referencia las figuras anexas que pretenden ser ilustrativas de las características de la invención, y que no det> en considerarse limitativas cié las diferentes modificaciorαes que podrán hacerse evidentes para una persona con conocimientos en el arte, a la luz de la presente descripción.Next, a more detailed description of the device of the invention will be made, taking as reference the attached figures that are intended to be illustrative of the features of the invention, and which do not stop being considered as limiting when the different modifications that may be made evident to a person with knowledge in art, in the light of this description.
Con referencia a la Figura 1, que muestra una primer modalidad de un dispositivo que .incorpora las características de la presente invención, se observa que el dispositivo ( 100) está constituido por un .anillo exteriorWith reference to Figure 1, which shows a first embodiment of a device that incorporates the characteristics of the present invention, it is observed that the device (100) is constituted by an outer ring.
(110) de forma esencialmente de cilindro recto, un anillo interior (120) también de forma esencialmente de cilindro recto, localizado concéntricamente respecto del anillo exterior (1IL0) y que es mantenido en esa relación concéntrica por medio de una pluralidad de elementos de unión (180) cχτ_ie son esencialmente broches en forma de arpón, que se atrapan entre si, de grosor constant e que van desde la cara exterrna del anillo interior (120) hacia la cara interna del arxillo exterior (110).(110) essentially of a straight cylinder, an inner ring (120) also essentially of a straight cylinder, located concentrically with respect to the outer ring (1IL0) and which is maintained in that concentric relationship by means of a plurality of connecting elements (180) cχτ_ie are essentially harpoon-shaped brooches, which are trapped together, of constant thickness and ranging from the outer face of the inner ring (120) towards the inner face of the outer ring (110).
El conjunto de anillo exterior (110), anillo intezrior (120) y la plurald_dad de elementos de unión, déte rminan un conjunto de orificios (160) cuya configuración geométrica final se determina básicamente por las paredes de los elementos de unión (180), la cara exterior del anillo interior (120) y la cara interior del anillo exterior (110), pero que puede ser alterada por la adición de una superficie de refuerzo (IL 90), plana y transversal a los semicírculos.The outer ring assembly (110), inner ring (120) and the plurality of connecting elements, give a set of holes (160) whose final geometric configuration is basically determined by the walls of the connecting elements (180), the outer face of the inner ring (120) and the inner face of the outer ring (110), but which can be altered by the addition of a reinforcement surface (IL 90), flat and transverse to the semicircles.
El conjunto ( 100) se divide en dos secciones esencialmente semicirculares por una linea diametral de corte (130) que divide el anillo interior (120) en su totalidad, el anillo exterior (110) exclusivamente en un extremo del ¿Liámetro, y la superficie de refuerzo (190) sobre dicho diámetro, quedando ambas secciones semicirculares unidas entre si por una área de material no cortado del anillo exterrior (110), una zona flexible (170) que hace las veces de bi_ sagra para permitir la abertura y cierre de dichas secciones semicirculares, como se ilustra en la Figura 2; era la que se observa que los lados de la linea diametral de corte (130) conforman una boca o abertura de entrada hacia el anillo interior (12O) . En adelante se empleará el numeral (130) para referir indistintamente a la linea de corte como a la boca que determina.The assembly (100) is divided into two essentially semicircular sections by a diametral cutting line (130) that divides the entire inner ring (120), the outer ring (110) exclusively at one end of the del Diameter, and the surface of reinforcement (190) on said diameter, both semicircular sections being joined together by an area of uncut material of the outer ring (110), a flexible zone (170) that acts as a bi_grain to allow the opening and closing of said semicircular sections, as illustrated in Figure 2; it was observed that the sides of the diametral cutting line (130) form a mouth or inlet opening towards the inner ring (12O). From now on the numeral (130) will be used to refer interchangeably to the line of cut as to the mouth that determines.
Se aprecia en las Figuras 1 a 3, que la cara interior del área del anillo exterior (110) que define la zona flexible (170), carece de superficie de refuerzo (160) para garantizar precisamente la flexibilidad de esa zona.It can be seen in Figures 1 to 3, that the inner face of the outer ring area (110) defining the flexible zone (170) lacks a reinforcing surface (160) to precisely guarantee the flexibility of that area.
El dispositivo (100) está, diseñado entonces para que un elemento estructural alargado, tal como una varilla metálica o un elemento de refuerzo similar, preferentemente con una sección transversal circular, pero no limitado a ello, pueda pasar libremente por la Iboca (130) cuando el dispositivo está en su posición abierta o de no uso, hasta alcanzar el espapio hueco definido por el anillo interior (120); una vez en su sitio el elemento alargado, el dispositivo se cierra, al flexionar la zona fLexible (170) de manera que los extremos opuestos de la boca (130) se encuentren en proximidad.The device (100) is then designed so that an elongated structural element, such as a metal rod or a similar reinforcement element, preferably with a circular cross-section, but not limited thereto, can freely pass through the Iboca (130) when the device is in its open or non-used position, until the hollow space is defined by the inner ring (120); once the elongated element is in place, the device closes, by flexing the flexible zone (170) so that the opposite ends of the mouth (130) are in proximity.
Una vez colocado en su sitio el dispositivo, es claro que el elemento estructural ocupa, justamente el centro del mismo, γ~ que dicho elemento estructural se encontrará siempre a una- distancia por lo menos igual la longitud entre su superficie: exterior y aquella del ani.Ho exterior (110), con respecto a_ cualquier superficie de referencia que esté en contacto son dicha cara exterior del anillo exterior (110) . Ya que no es necesario que el elemento estructural alargado tenga una medida diametral tal que se ajuste al anillo interior (120), el dispositivo permanece en relación rotable alrededor de su propio eje, mismo que coincide con el eje longitudinal del elemento estructural alargado en su interior; esta característica es sumamente útil incluso por ejemplo, cuando una estructura metálica formada por una pluralidad de elementos estructurales dispuestos en forma de malla, debe deslizarse en una. perforación tal como un pozo excavado directamente en el suelo, donde una pluralidad de dispositivos como el de la invención se distribuyen en la malla de manera que funcionan como rodajas para permitir el fácil deslizamiento del conjunto, y una vez que éste se encuentra en su posición final, garantizan que los elementos estructurales a los que se han asociado, se encuentren a la distancia predefinida de las paredes de dicho pozo.Once the device is in place, it is clear that the structural element occupies, just the center of it, γ ~ that said structural element will always be at least equal distance between its surface: exterior and that of the ani.Ho exterior (110), with respect to_ any reference surface that is in contact are said outer face of the outer ring (110). Since it is not necessary for the elongated structural element to have a diametral measurement such that it fits the inner ring (120), the device remains in rotatable relationship around its own axis, which coincides with the longitudinal axis of the elongated structural element in its inside; this characteristic is extremely useful even for example, when a metal structure formed by a plurality of structural elements arranged in a mesh form, must slide into one. drilling such as a well dug directly into the ground, where a plurality of devices such as that of the invention are distributed in the mesh so that they function as slices to allow easy sliding of the assembly, and once it is in position In the end, they guarantee that the structural elements to which they have been associated are located at the predefined distance from the walls of said well.
Para asegurar que el dispositivo se mantenga en posición respecto del elemento alargado localizado en su centro, el dispositivo cuenta con una pluralidad de medios de acoplamiento y aseguramiento, siendo dichos medios de acoplamiento constituidos por un primer gancho acoplable con un segundo gancho (receptor) , localizados preferentemente de la siguiente manera:To ensure that the device is held in position with respect to the elongate element located at its center, the device has a plurality of coupling and securing means, said coupling means being constituted by a first hook attachable with a second hook (receiver), preferably located as follows:
1. dos de los primeros ganchos (150) se forman del mismo material del dispositivo, como prolongaciones de los extremos del semicírculo que formará el anillo interior (120), localizándose de manera próxima a uno de los bordes más externos del cilindro definido por dicho anillo interior (120), y siendo opuestos entre sí (frente a frente) ;1. Two of the first hooks (150) are formed of the same material of the device, as extensions of the ends of the semicircle that will form the inner ring (120), being located close to one of the outermost edges of the cylinder defined by said inner ring (120), and being opposite each other (face to face);
2. dos de los segundos ganchos (151) (receptores) se forman del mismo material del dispositivo, como prolongaciones de 1 os extremos del semicírcuILo que formará el anillo interior (120), localizados en los extremos de la sección semicircular opuesta a los primeros ganchos, y e≥n relación operable con aquellos;2. Two of the second hooks (151) (receivers) are formed from the same material of the device, such as extensions of the ends of the semicircle that will form the inner ring (120), located at the ends of the semicircular section opposite the first hooks, and operable relationship with those;
los medios de acoplamiento (150) y (151) ocupan solamente la porción más externa próxima a uno de los bordes del ci±lindro definido por el anillo interior (120), y se aprecia de las Figuras 1 a 3 que se encuentran en relación simétrica; los ganchos receptores (151) están limitados hacia la parte media de la superficie exterior del cilindro determinado por el anillo interior (120) , por el cuerpo de los elementos de unión (180) que corresponden con la posición de dichos ganchos receptores (151) de manera que dichos elementos de unión (180) determinan τ_m tope para los correspondientes ganchos (150), que no piαeden desplazarse en esa dirección una vez que alcanzan el borde exterior de dichos elementos de unión (180) correspondientes. De manera similar, en la otra cara del dispositivo, se distinguen:the coupling means (150) and (151) occupy only the outermost portion near one of the edges of the cylinder defined by the inner ring (120), and can be seen from Figures 1 to 3 which are in relation symmetric; the receiving hooks (151) are limited towards the middle part of the outer surface of the cylinder determined by the inner ring (120), by the body of the connecting elements (180) corresponding to the position of said receiving hooks (151) so that said joining elements (180) determine τ_m stop for the corresponding hooks (150), which cannot move in that direction once they reach the outer edge of said corresponding joining elements (180). Similarly, on the other side of the device, they are distinguished:
3. dos de los primeros ganchos (150) se forman del mismo material del dispos itivo, como prolongaciones de los extremos del semicírculo que formará el anillo interior3. Two of the first hooks (150) are formed of the same material of the device, as extensions of the ends of the semicircle that will form the inner ring
(120), localizándose de manera próxima a uno de los bordes más externos del cilindro definido por dicho anillo interior (120), y siendo opuestos entre si(120), being located close to one of the outermost edges of the cylinder defined by said inner ring (120), and being opposite each other
(frente a frente); y 4. dos de los segundos ganchos (151) (receptores) se forman del mismo material del dispositivo, como prolongaciones de ios extremos del semicírculo que formará el anillo interior (120), localizados en los extremos de la sección semicircular opuesta a los primeros ganchos, y en relación operable con aquellos;(facing); and 4. two of the second hooks (151) (receivers) are formed of the same material of the device, such as extensions of the ends of the semicircle that will form the inner ring (120), located at the ends of the semicircular section opposite the first hooks, and in operable relationship with those;
observándose en las Figuαras 1 a 3 que los ganchos (150) de la segunda cara se localizan en la misma sección semicircular que los ganchos receptores (151) de la primera cara y viceversa. De esta manera, ninguno de los pares de ganchos (150), (151) que conforman los medios de acoplamiento, pueden realizar un desplazamiento en la dirección longitudinal al eje de rotación., del dispositivo en ningún sentido: más aún, debido a la di sposición simétrica en dos pILanos, es prácticamente imposible que los medios de acoplamiento se desacoplen inadvertidamente, y solamente pueden ser desacoplados al ejercer urna fuerza con la magnitud, dirección y Sentido adecuados sobre los cuatro pares de ganchos de manera simultánea. ITodo ello brinda al conjunto una estabilidad superior en su configuración, con respecto a los dispositivos conocidos en el arte.it is observed in Figures 1 to 3 that the hooks (150) of the second face are located in the same semicircular section as the receiving hooks (151) of the first face and vice versa. In this way, none of the pairs of hooks (150), (151) that make up the coupling means, can make a displacement in the longitudinal direction to the axis of rotation., of the device in no sense: moreover, due to the symmetrical arrangement in two pILANS, it is practically it is impossible for the coupling means to be inadvertently disengaged, and they can only be decoupled by exerting force with the appropriate magnitude, direction and direction on the four pairs of hooks simultaneously. All this gives the set a superior stability in its configuration, with respect to the devices known in the art.
En una segunda modalidad, mostrada en las Figuras 4 a 7, se observa que el dispositivo (200) está constituido de la misma manera que la primer modalidad ilustrada en las Figuras 1 a 3, con un anillo exterior (210) de forma esencialmente de cilindro recto, un anillo interior (220) también de forma esencialmente de cilindzro recto, localizado concéntricamente respecto del anillo exterior (210) y que es mantenido en esa relación concéntrica por medio de una pluralidad de elementos de unión (280) qxαe son esencialmente tiras de grosor constante que van desde la cara externa del anillo iLnterior (220) hacia la cara interna del anillo exterior (210) . Sin embargo, en esta modalidad, el ancho de los elementos de unión (280) va en aumento desde el anillo exterior (210) hasta alcanzar su máximo en la linea de contacto con el anillo interior (220); este incremento de anchura en las proximidades del elemento alaurgado aumentan la estabilidad del dispositivo en la estructura una vez acoplado a dicho elemento alargado.In a second embodiment, shown in Figures 4 to 7, it is observed that the device (200) is constituted in the same manner as the first mode illustrated in Figures 1 to 3, with an outer ring (210) essentially in the form of straight cylinder, an inner ring (220) also essentially in the form of a straight cylinder, located concentrically with respect to the outer ring (210) and which is maintained in that concentric relationship by means of a plurality of connecting elements (280) qxαe are essentially strips of constant thickness ranging from the outer face of the inner ring (220) to the inner face of the outer ring (210). However, in this mode, the width of the connecting elements (280) is increasing from the ring exterior (210) until reaching its maximum in the line of contact with the inner ring (220); This increase in width in the vicinity of the flanged element increases the stability of the device in the structure once coupled to said elongated element.
El conju.nto de anillo exterior (210), anillo interior (220) y la pluralidad de elementos de unión, determinan un conjunto de orificios (260) cuya configuración geométrica final s e determina básicamente por las paredes de los elementos de unión (280), la cara exterior del anillo interiorr (220) y la cara interior del anillo exterior (210), pero que puede ser alterada por la adición de una superficie de refuerzo (290), como se describió anteriorrmente para la primera modalidad. En el' ejemplo ilustrado, di_chos orificios (260) son preferentemente circulares, con excepción de aquellos que se corresponden con la linea de abertura o boca (230) . En la modalidad ilustrada, a la sección (290) se le añade una costilla paralela o en el mismo sentido de los semicírculos, logrando mayor rigidez par'a Los modelos de diámetros superiores.The outer ring conjuction (210), inner ring (220) and the plurality of joining elements, determine a set of holes (260) whose final geometric configuration is basically determined by the walls of the joining elements (280) , the outer face of the inner ring (220) and the inner face of the outer ring (210), but which can be altered by the addition of a reinforcing surface (290), as described above for the first embodiment. In the 'illustrated, di_chos holes (260) are preferably circular, except those corresponding to the opening or mouth line (230). In the illustrated mode, a parallel rib or in the same direction of the semicircles is added to section (290), achieving greater rigidity for higher diameter models.
El anillo exterior también ostenta una zona (270) flexible que permite el movimiento abisagrado de las dos secciones semicirculares que, cuando el dispositivo es ~tá en posición de uso han de cerrarse alrededor del elemento al argado para que el dispositivo opere como distanciador .The outer ring also holds a flexible area (270) allowing hinging of the two semicircular sections movement, when the device is in position ~ tá of use they must be closed around the element to the argado so that the device operates as a spacer.
Se aprecia en las Figuras 4 a 7, que la cara interior del área del anillo exterior (210) que define la zona flexible (270), carece de superficie de refuerzo (260) para garantizar precisamente la flexibilidad de esa zona.It can be seen in Figures 4 to 7, that the inner face of the area of the outer ring (210) defining the flexible zone (270) lacks a reinforcing surface (260) to precisely guarantee the flexibility of that area.
De manera s imilar a la primer modalidad ilustrada, el dispositivo de la segunda modalidad incorpora una. pluralidad de elementos de sujeción (250), (251) cooperables entre si y dispuestos simétricamente en los extremos de los semicírculos del anillo interior (220) tanto dismetralmente como con rrespecto al plano medio que atraviesa al dispositivo. También se presentan elementos cde sujeciónIn a similar way to the first mode illustrated, the device of the second mode incorporates one. plurality of fasteners (250), (251) cooperable with each other and arranged symmetrically at the ends of the semicircles of the inner ring (220) both dismetrically and with respect to the median plane running through the device. Clamping elements are also presented
(240), (241) en los extremos opuestos de la boca (230) . Debe notarse que la simetría respecto del plano medio del dispositivo se aprecia mejor en la Figura 7, respecto de los elementos de sujeción (240) y (241) en el anilLlo exterior (210) y (250) y (251) en el anillo interior (220) .(240), (241) at opposite ends of the mouth (230). It should be noted that the symmetry with respect to the middle plane of the device is best seen in Figure 7, with respect to the fasteners (240) and (241) in the outer ring (210) and (250) and (251) in the ring interior (220).
En la Figura. 8, se ilustra una tercer modalida_d (300) del dispositivo materia de la presente invención. En ella, la superficie exterior del anillo exterior (310) se encuentra cubierta po x una pluralidad de proyecciones hacia el exterior del dispositivo (300), equidistantes entre si, de manera tal que el contacto con una superficie de referencia se limita al extremo de dichas proyecciones. Esto es úitil en aquellos casos en que la superficie terminada de concreto requiera tener una mínima evidencia del materia.1 del distanci ador . Las proyecciones pueden tener prácticamente cualquier forma pero se prefieren aquellos perfiles en que el área de contacto con la superficie de referencia sea mínima, como por ejemplo, triángulos truncos (trapezoides) o proyecciones rectangulares u oblongas.In the figure. 8, a third modality_d (300) of the subject device of the present invention is illustrated. In it, the outer surface of the outer ring (310) is covered by a plurality of projections towards the outside the device (300), equidistant from each other, such that contact with a reference surface is limited to the end of said projections. This is useful in those cases where the finished concrete surface requires having minimal evidence of the matter.1 of the distance. The projections may have virtually any shape but those profiles in which the contact area with the reference surface is minimal, such as truncated triangles (trapezoids) or rectangular or oblong projections are preferred.
Finalmente, en la Figura 9, se muestra esquemáticamen~fce cómo se dispone el dispositivo de la invención en su posición de uso, ilustrando esto con base en la primer modalidad! de la presente invención, en la que solamente se denotan con numerales algunos de los elementos ya ilustrado en las figuras precedentes, apreciándose claramente en la figura que el elemento estructural alargado, se sitúa en eZL hueco del anillo central, sin tocar sus paredes de manera ajustada, por lo que el dispositivo puede rotar lib remente alrededor de dicho elemento estructural al argado, manteniendo una distancia con la pared externa del anillo exterior, prácticamente constante, permitiendo además que una estructura completa pueda deslizarse por las par&des de, por ejemplo, una cimbra o las paredes de un pozo, empleando los dispositivos distanciadores de la invención como rodaj as , asegurando la posición final de dicha e structura a la distancia predeterminada de la superficie de referencia .Finally, in Figure 9, esquemáticamen ~ fce shown how the device of the invention is disposed in its use position, illustrating that based on the first embodiment! of the present invention, in which only some of the elements already illustrated in the preceding figures are denoted with numerals, clearly showing in the figure that the elongated structural element is located in the hollow eZL of the central ring, without touching its walls so adjusted, so that the device can freely rotate around said structural element to the armature, maintaining a distance with the outer wall of the outer ring, practically constant, also allowing a complete structure to slide along the sides of, for example, a formwork or the walls of a well, using the distance devices of the invention as slices, ensuring the final position of said structure at the predetermined distance from the reference surface.
